LogicalConstant¶
A logical literal.
Declaration¶
Syntax¶
LogicalConstant(bool value, ttype type)
Arguments¶
Argument |
Description |
|---|---|
|
|
|
the logical type, which fixes the kind and therefore the storage size. |
Return values¶
The value of the expression.
Description¶
The default logical kind is 4, matching the default integer kind, so a logical occupies the same storage as an integer unless another kind is asked for.
Examples¶
(LogicalConstant
:value true
:type (Logical
:kind 4
)
)
